Robot for assisting the muscular strength of lower extremity and control method for walking of the same

TL;DR: In this paper, a walking control method for the lower extremities of the human body and a walking controller for controlling the locomotion of the robot is provided to control the operation by sensing the volume change of muscle.
Abstract: PURPOSE: A muscular strength supplementary robot for the lower extremities of human body and a walking control method thereof are provided to control the operation by sensing the volume change of muscle and to control the locomotion of the muscular strength supplementary robot for the lower extremities of the human. CONSTITUTION: A muscular strength supplementary robot for the lower extremities of human body includes: an auxiliary tool(100) which is equipped with a plurality of wearing parts for the human body and covers the top and bottom of the knee; an exoskeleton(200) which is equipped with a wrist and an upper skeleton in the knee location and a lower skeleton and is coupled with the outside of the auxiliary tool; an actuator(300) which rotates the upper and lower skeletons; a sensor(400) which is attached to the human body and senses the volume change of muscle; and a controller which transforms the operating signal into the actuator after the operation will signal of the human body is decided based on the value outputted from the sensor.

TL;DR: In this paper, a walking aiding robot is presented to assist a patient in walking on the flat ground, but also in walking upstairs and downstairs, bringing great convenience to the life of the patient.
Abstract: The invention discloses a walking aiding robot. A lower limb walking mechanism of the robot comprises a hip joint rotating mechanism, a knee joint rotating mechanism, and a support assembly of an ankle joint rotating mechanism; a body bearing piece, a battery, and a controller matched with a body are installed on the support assembly, and the controller is connected with the hip joint rotating mechanism, the knee joint rotating mechanism and the ankle joint rotating mechanism separately; a remote-controller connected with the controller can operate and control actions of the lower limb walking mechanism. The robot can help a patient accomplish standing or walking training, so that bedsore, amyotrophy and osteoporosis are prevented, muscle spasm and deformity of joint are reduced, the living quality of the patient is maintained, and part of the self-care ability of daily living is regained; besides, the robot can not only assist the patient in walking on the flat ground, but also in walking upstairs and downstairs, bringing great convenience to the life of the patient.

TL;DR: In this article, a leg support assistance device which has a rotary type automatic arthrodesis apparatus and an operating method thereof are provided to stably support a body while working in a standing position with the legs bent by selectively limiting or blocking a circulation around a leg joint.
Abstract: PURPOSE: A leg support assistance device which has a rotary type automatic arthrodesis apparatus and an operating method thereof are provided to stably support a body while working in a standing position with the legs bent by selectively limiting or blocking a circulation around a leg joint thereby automatically fixing the joint according to the choice of a wearer. CONSTITUTION: A leg support assistance device which has a rotary type automatic arthrodesis apparatus comprises: a top brace (100) which has a structure capable of attaching and detaching, and which is located in the upper part of the leg joints; a lower part brace (200) which has the structure capable of attaching and detaching, and which is located in the lower part of the leg joints; and an arthrodesis part (300) which selectively limits a circulation of the brace. An operating method of the leg support assistance device comprises the following steps. A motion detection sensor senses a movement of a wearer. The joint is fixed by blocking the circulation of the brace by operating the arthrodesis part in case the movement is not detected for a certain time. The arthrodesis part releases the blocking of the brace when the variation value which is measured in the pressure sensor or the strain gauge is greater than the pre-set value (Δα). When the variation value which is measured in the pressure sensor or the strain gauge is less than the pre-set value (Δα), the arthrodesis part blocks the circulation and fixes the joint until the variation value is greater than the pre-set value (Δα).

TL;DR: In this article, a leg support aid having a rotary-type automatic joint locking device, and a method for operating same, is presented, where a simple and convenient structure is used to selectively restrict or block the pivoting of the leg joint by user selection and the joint can be fixed and released automatically and at various angles, and thus the body can be stably supported in a state where standing is required.
Abstract: The present invention relates to a leg support aid having a rotary-type automatic joint locking device, and to a method for operating same. The present invention comprises: a removable upper brace (100) that is disposed at the upper portion of a leg joint in order to support the leg; a removable lower brace (200) that is disposed at the lower portion of the leg joint in order to support the leg; and a joint locking unit (300) that selectively restricts the pivoting of the braces and is configured of a rotary cylinder (330) connected to the side surface of the upper brace (100) and/or the lower brace (200) in the case where the upper brace and the lower brace (200) pivot about the leg joint, a partition wall lever (333) that is fixed to the upper brace and divides the rotary cylinder into two spaces filled with a fluid, a connection pipe (335) connected to the two spaces in the lower portion of the rotary cylinder (330) so as to move the fluid, and an actuator (350) that blocks the movement of the fluid through the connection pipe (335). According to the present invention, a simple and convenient structure is used to selectively restrict or block the pivoting of the leg joint by user selection and the joint can be fixed and released automatically and at various angles, and thus the body can be stably supported in a state where standing is required with the leg joint being bent.
